Creating random csv file

Function creates random CSV file. Remember the size is approximate

Example invocation:

file name index.js

const parser = require('csv-json-parser-module');

parser.bigFile(process.argv);

process.argv is required as the params are taken from the terminal

Then you can call it in the terminal with:

node index filePath="FILE_PATH" size=SIZE

FILE_PATH is a place where you want to create CSV

Valid parameters

When passing the file path remember about commas around. Else it maybe split and cause error message

Size is considered in GB. If you want less take it under consideration

Example invocation:

file name index.js

const parser = require('csv-json-parser-module');

(async () => {
  await parser.csvParser(process.argv)
  process.exit()
})();

The process needs to be stopped explicitly else it won't break by itself
